What should i buy (football/soccer related)?

i have 100$ and i get 20$ each time i see my grandpa which is usually every or every other week. my mom is already getting me puma tokyo power cat cleats for the year so i don't need cleats. i have about 3-4 so i don't need a new ball. I also don't have the space for a net or goal. i was thinking maybe getting a jersey? I'm not sure. any ideas you guys have?
